There are 10 different processes running on a workstation. Idle processes are waiting for an input event in the input queue. Busy processes are scheduled with the Round- Robin time sharing method. Which out of the following quantum times is the best value for small response times, if the processes have a short runtime, e.g. less than 10ms?
A)tq = 15ms
B)tq = 40ms
C)tq = 45ms
D)tq = 50ms

Question

For processes with short runtimes (less than 10ms), a smaller quantum time ensures that processes are switched out quickly, allowing for a more responsive system. A quantum time of 15ms (option A) is closest to the process runtime, minimizing overhead and improving response times compared to the larger quantum times listed.
